By his own admission, Ben is no Einstein. He's flitted from job to job while partying and keeping his cock wet. If he wasn't inducted into military service this boy would end up wandering the streets and getting up to no good. He may say he is in good nick but the sergeants need to ensure that his body is in fighting condition. He's undressed down till he's stark bollock naked next to the superiors who are clothed in their camouflage. The hapless lad can't help growing a big stiff erection.
